HCFC-141 and HCFC-141b are ozone-depleting substances subject to phasedown controls under the Montreal Protocol, which directly shapes US import licensing and quota requirements administered by the EPA. Classified under a single 10-digit line (2903730100), these compounds have historically served as foam-blowing agents and cleaning solvents, though regulatory restrictions have significantly narrowed their permitted end uses. Canada is the dominant US import source, a supply relationship facilitated by USMCA proximity and integrated North American chemical manufacturing.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Yes. The EPA administers an allowance system under the Clean Air Act implementing the Montreal Protocol phasedown. Importers must hold sufficient consumption allowances before bringing HCFC-141b into the US, and shipments are subject to EPA reporting requirements at entry.
Allowable uses have narrowed substantially under the phasedown schedule. Remaining permitted imports are generally limited to specific servicing or feedstock applications; importers should confirm current EPA allowance eligibility before contracting supply, as unauthorized use can trigger enforcement action.
